My boss is trying to get rid of me due to my disease.

My group was transferred within the company 4 months ago, with the same job duties as before. I have a long term non-curable disease that gave me some physical disability (i.e. not being able to walk very far), but never affected my work performance. The disease has a potential to progress worse.

My new boss doesn’t like me at all. No matter what/how I do, nothing I did was right to him. He picks on everything I did, even the font I use for reports. The group has 3.5 staff members. But I have over half of the workload. I work at night and on the weekends trying to get things done. I brought to his attention repeatedly that I was overloaded and I can’t finish everything on time if he doesn’t redistribute the workload. And he gets angry with me for not meeting deadlines.

Now he got with the company’s medical and lawyer. They want me to go to my physician to have my physical, mental and cognitive abilities to be assessed objectively. It is obvious that he is trying to prove that I can’t perform the job duty and get rid of me.

What should I do? I need the job to support the family, and I don’t want to lose the battle.
